Can't Open Sampler Project File

I reported a major bug on Thursday, Feb. 2.  The issue is that Sampler suddenly will not open a Sampler project file that is critical to my work.  I reported the bug via Sampler's Report Bug feature.  A day later, I received a response from Baptiste saying the following:

"Can you try to delete the following folder /AppData/Adobe/Adobe Substance 3D Sampler and open your project again? Otherwise, can you send the project file ?"

I replied immediately on Friday morning with the following two questions:

1) Baptiste, for the delete, are you referring to the "Adobe Substance 3D Sampler" subfolder in the "Local" ( C:/Users/Me/AppData/Local ) or "Roaming" ( C:/Users/Me/AppData/Roaming ) folder?

2) I'll try deleting the referenced file and see what happens. If I need to send you the file that is not opening, how would you like for me to send it? I can use Dropsend, which sends you a download link via email. Will this work for you?

It is now Monday mid-day (4 days after I reported this major issue which is affecting my workflow in a big way) and Baptiste still has not answered my two simple, yet important, questions.  

LoryAline, do you know the answers to these two questions or are you able to get Baptiste to respond?  I do this work professionally and have been paying for Adobe products for the last 30 years.  It would be nice to get a more timely response when I have been kind enough to report dozens of bugs in your software over the past several years.

Thank you.
